Mobile App for Goods Receiving with Barcode Scanning

When receiving goods at the warehouse, an operator spends 15 minutes manually entering 50 boxes. With our app, it takes 2 minutes. Replacing paper documents and manual entry with scanning and automatic verification against the Purchase Order (PO) — a real case we implemented at a warehouse with 100 daily receipts. Time savings: 8 hours of staff work daily, error reduction from 5% to 0.5%. The solution is a mobile app with a built-in barcode and Data Matrix scanner.

How Automation with Scanner Speeds Up Receiving by 5x

Manual receiving leads to delays, input errors, and disputes with suppliers. A barcode scanner speeds up the process by 3–5 times: the operator no longer needs to enter SKUs and quantities by hand. Parsing GS1-128 allows extracting GTIN, lot number, expiry date, and quantity from a single barcode. According to GS1 General Specifications, this format supports up to 48 digits. For example, a pallet with SSCC provides all data about the boxes inside immediately. We integrated GS1-128 and Data Matrix, including Chestny Znak marking codes. Additionally, EAN-13, ITF-14, Code 128, and QR are supported — a full set for any supplier.

Scanning Data Matrix for Mandatory Marking

For goods subject to mandatory marking (Chestny Znak), Data Matrix is the only format meeting legal requirements. The app parses the cryptotail, checks the code online via the Chestny Znak API, and records the status — allowed for sale, blocked, or expired. This prevents acceptance of counterfeit goods and fines under Federal Law 54-FZ. Photo capture of defects at this stage allows documenting damage and attaching it to the discrepancy report TORG-2.

Verification Against Purchase Order: Workflow

The primary scenario: load the Purchase Order (PO) before receiving, scan incoming goods, and compare actuals with the plan in real time.

data class ReceivingLine( val poLineId: String, val sku: String, val gtin: String, val orderedQty: Double, val receivedQty: Double = 0.0, val lotNumber: String? = null, val expiryDate: LocalDate? = null, val status: LineStatus = LineStatus.PENDING ) class ReceivingViewModel : ViewModel() { fun processScan(parsedBarcode: Map<String, String>) { val gtin = parsedBarcode["01"] ?: parsedBarcode["02"] ?: return val lot = parsedBarcode["10"] val expiry = parsedBarcode["17"]?.let { parseExpiry(it) } val qty = parsedBarcode["37"]?.toDoubleOrNull() ?: 1.0 val line = findLineByGtin(gtin) ?: run { // товар не в PO — предупреждение, фиксируем как неожиданный recordUnexpectedItem(gtin, qty) return } val updated = line.copy( receivedQty = line.receivedQty + qty, lotNumber = lot ?: line.lotNumber, expiryDate = expiry ?: line.expiryDate, status = when { line.receivedQty + qty > line.orderedQty * 1.05 -> LineStatus.OVER_RECEIVED abs(line.receivedQty + qty - line.orderedQty) < 0.01 -> LineStatus.COMPLETED else -> LineStatus.IN_PROGRESS } ) updateLine(updated) } } 

Over-receiving and under-receiving both require visual warnings. Color coding: green (within tolerance), yellow (minor discrepancy), red (significant overage or defect). Additionally, photos of damages are captured — each image is linked to the report line and stored in S3 with a time-limited URL. Delivery verification at this stage guarantees inventory accuracy.

What to Do When Discrepancies Occur?

If scanning reveals overages or shortages, the app prompts the operator to photograph the problematic item and generate a TORG-2 discrepancy report. The document can be sent to the supplier immediately via email. For warehouse inventory, this feature helps quickly identify systematic delivery errors.

How to Set Up GS1-128 Scanning: Step-by-Step Instructions

1. Connect the scanner to the device via Bluetooth.
2. Open the app and select "Receiving".
3. Point the camera at the GS1-128 barcode.
4. Verify the recognized data: GTIN, lot, expiry, quantity.
5. Confirm the receipt — data is automatically matched against the PO.

Receiving Speed Comparison

For a warehouse with 100 daily receipts, the savings are about 8 hours of staff labor. Savings from reduced fines and increased turnover can be significant. Automated receiving is 3–5 times faster and 10 times more accurate than manual.

Integration with Chestny Znak

The app automatically validates each Data Matrix code via the Chestny Znak API. If the code has already been withdrawn from circulation or counterfeited, the operator receives a warning. Upon completion of receiving, a report listing all verified codes is generated, reducing the risk of claims from regulatory authorities. This procedure can be configured to send automatically via email or direct push to WMS.
